Proximal migration of ventriculoperitoneal (VP) shunt is extremely rare. A medium pressure VP shunt was inserted in a 10-month-old infant suffering from severe hydrocephalus. One month later, complete migration of the shunt into the lateral ventricle was encountered. Possible causative mechanisms and the literature on this subject are briefly discussed.
A case of lymphocytic hypophysitis (LYHY) in a menopausal woman is presented. A review of the literature suggests that conservative treatment may be tried in suspected cases of LYHY, if the vision of the patient is not threatened. A transphenoidal stereotactic biopsy of the mass may be performed if the patient fails to improve or deteriorates, thus avoiding open exploration of the sella in selected cases.
Syringomyelia following meningitis is a rare condition. This report summarizes the history of a 43 year old Indian male who developed arachnoiditis as a sequalae of tubercular meningitis. This later progressed to syringomyelia. The patient was treated with a syringo-subarachnoid shunt.
Three cases of solitary osteochondroma of the spine are reported. Two pre sented with cervical myelopathy and one with radiculopathy. Plain radiography or tomography is adequate for the diagnosis in the majority of cases; neverthe less, a CT scan or MRI is of immense help in planning surgical treatment. The radiological features of spinal exostoses are reviewed.Key words: spinal osteochondroma; cervical myelopathy; cervical radiculopathy. (Fig 1).
Meningeal melanocytoma is a rare pigmented tumor of the leptomeningeal melanocytes. This rare entity results in diagnostic difficulty in imaging unless clinical and histopathology correlation is performed. In this case report, we describe a case of meningeal melanocytoma of the cervical region presenting with superficial siderosis. Extensive neuroradiological examination is necessary to locate the source of the bleeding in such patients. Usually, the patient will be cured by the complete surgical excision of the lesion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
